Abstract
The new geospatial data of the Friuli Venezia Giulia Region (Italy): a geomatic challenge
Highlights
The second realization of considerable quality is the ortophotomosaic of the entire territory, based on the generation of “True” orthophoto, acquired on 4 bands (RGB and NIR), with a pixel size of 10 cm and a georeferencing tolerance of less than 35 cm
The FVG Region started in 2017 the radical renewal of its geospatial databases, expanding them with new cartographic products, and entrusting the realization to a group of private firms specialized in the necessary geomatic techniques
Further raster maps were elaborated at 0.5 meter intervals, such as the digital land surface (DSM) derived from the "first returns" and that produced with the "last returns", the digital terrain model (DTM), the building model (DBM) and other specific products
Summary
The second realization of considerable quality is the ortophotomosaic of the entire territory, based on the generation of “True” orthophoto, acquired on 4 bands (RGB and NIR), with a pixel size of 10 cm and a georeferencing tolerance of less than 35 cm. In order to have adequate tools for analysis and planning, the regional administration maintains a complete, updated and accurate mapping of the territory, investing adequate resources in the acquisition of advanced cartographic products.
